Polly, the 18 month old matriarch of the flock has been in a listless stage for about two weeks now. It began with her molt and I initially thought she was just grumpy because of her nakedness. I noticed though that she has diarrhea and also does not go for the feed (had switched back to grower ration to provide more protein for the molting girls) or the beloved scratch. She moves with the flock, and does appear to eat worms and vegetation. Her comb is paler than usual and she just isn't quite herself. The diarrhea concerns me. It is very watery, however not bloody. I have considered coccidosis, but then I would have to assume that the whole flock should be affected. Any input on this would be greatly appreciated. Thanks!
